There's a thread on the forum about 12 pages long discussing DAFNE from the graduates who have completed the course, I'd have provided a link but the forum is running painfully slow again and doesn't seem to want to search for it, I'll post sometime over the weekend for you Twinks.
I did the course back in 2009, have to say it was very worthwhile and enjoyed the whole experience. Basically they teach you to carb count and show you who to work out your insulin to carb ratio's, they also go into great detail about basal insulin's and how to adjust them, the Sick Day Rules are invaluable (as is the exercise advice) and a whole afternoon is devoted over to this very topic, if patients want to they can ask partners, family or friends to come in for the SDR session so that they can learn too.
Just about everything to do with type 1 management is discussed on the course and there's a Q & A session with the Endo's and DSN's for those that have any questions to ask at the end, the only thing that isn't discussed on the course is diet, DAFNE suggest that eating healthy is personal choice which I tend to agree with!!
